ATLANTA - A Gainesville doctor convicted of downloading child pornography and using boys to produce sexually explicit pictures is seeking to delay his sentencing scheduled for later this month.

The government wants to use allegations that Gregory Kapordelis molested children in Russia to get him a tougher sentence, but the defense says the claims are irrelevant to the porn conviction, according to court papers.

Federal sentencing guidelines call for Kapordelis to receive about 15 years in prison, though prosecutors will urge a judge to depart from the guidelines and give the anesthesiologist a longer sentence, the defendant's lawyer, Don Samuel, said in an interview Tuesday.

Samuel, who is seeking a new trial for his client, said he will ask for a sentence of less than 15 years. The maximum penalty Kapordelis faces is up to 95 years in prison, prosecutors have said.

Kapordelis was convicted by a federal jury May 24 of six counts of downloading child pornography and using boys to produce pornographic pictures between 2001 and 2004.

He was acquitted of a seventh count accusing him of making a video of himself having sex with a person under 18.

Sentencing was initially scheduled for Wednesday but was later postponed until Aug. 24. Samuel said in a court filing last week that he is seeking to delay the sentencing further so he can prepare his argument.

There was no ruling as of Tuesday on the request to further delay sentencing.

Patrick Crosby, a spokesman for the U.S. Attorney's Office in Atlanta, said the office had no comment on the case.
